DETAILED DESCRIPTION

Devices and network attached appliances part of the Internet of Thingsmay not be readily configured. Users may have difficulty remembering aparticular configuration or the process to perform the configuration.Further, backup solutions that require communication with a pre-definedglobal backup server may not be suitable to store configuration settingsfor network attached appliances because the appliance manufacturer maynot be able to provide long term commitments for server locations.

Described embodiments provide techniques for allowing network attachedappliances, such as devices and objects of the Internet of Things, tobackup and restore configuration settings by broadcasting backup andrestore requests to backup servers in a network designed to acceptbackup and restore requests from different clients that adhere to acommon backup and restore protocol. The backup and restore operationsand communications among network attached appliances and backup serversmay be session free, requiring no registration or authentication. Thebackup servers receiving the broadcasts may each independently backupconfiguration settings from the network attached appliances and provideconfiguration settings to restore requests from a network attachedappliance. Because backup and restore requests are broadcasted tonumerous backup servers independently providing the backup services, anyof the backup servers that are available may respond to backup andrestore requests for configuration settings when needed.

FIG. 1 illustrates an embodiment of a network computing environmenthaving a plurality of network attached appliances 100 ₁, 100 ₂ . . . 100_(m) and backup servers 102 ₁, 102 ₂ . . . 102 _(n) that communicateover a network 104. Each of the backup servers 102 ₁, 102 ₂ . . . 102_(n) may backup configuration settings in each of the network attachedappliances 100 ₁, 100 ₂ . . . 100 _(m). Each of the network attachedappliances 100 ₁, 100 ₂ . . . 100 _(m) include, as shown with respect tonetwork attached appliance 100 _(i), an embedded system 106 includingconfiguration settings 108 used to configure appliance hardware 110,comprising the device specific hardware of the network attachedappliance 100 _(i); a unique identifier 112 of the network attachedappliance 100 _(i) to uniquely identify the network attached appliance100 _(i) in the network; a backup/restore client 114 to performoperations to backup and restore the configuration settings 108 withrespect to the backup servers 102 ₁, 102 ₂ . . . 102 _(n); and a networkadaptor 116 to connect to the network 104. The network attachedappliances 100 ₁, 100 ₂ . . . 100 _(m) may comprise any type of consumeror other device that may connect to a network 104. For instance thenetwork attached appliances 100 ₁, 100 ₂ . . . 100 _(m) may compriseobjects characterized as part of the Internet of Things, such asdevices, vehicles, buildings, embedded with electronics, softwaresensors and network connectivity to allow those objects to communicateon the network 104.

The embedded system 106 may be implemented using a processor executing acomputer program in a storage device, such as described with respect toFIG. 10. Alternatively, the embedded system 106 may be implemented in anapplication specific integrated circuit (ASIC), such as a system-on-achip design.

Each of the backup servers 102 ₁, 102 ₂ . . . 102 _(n) include, as shownwith respect to backup server 102 _(i), a backup/restore server 118 anda configuration setting database 200 to store configuration settingsbroadcasted by the network attached appliances 100 ₁, 100 ₂ . . . 100_(m).

The backup servers 102 ₁, 102 ₂ . . . 102 _(n) may store theconfiguration setting database 120 in a storage 122 comprising one ormore storage devices known in the art, such as a solid state storagedevice (SSD) comprised of solid state electronics, EEPROM (ElectricallyErasable Programmable Read-Only Memory), flash memory, flash disk,Random Access Memory (RAM) drive, storage-class memory (SCM), PhaseChange Memory (PCM), resistive random access memory (RRAM), spintransfer torque memory (STM-RAM), conductive bridging RAM (CBRAM),magnetic hard disk drive, optical disk, tape, etc. The storage devicesmay further be configured into an array of devices, such as Just a Bunchof Disks (JBOD), Direct Access Storage Device (DASD), Redundant Array ofIndependent Disks (RAID) array, virtualization device, etc. Further, thestorage devices may comprise heterogeneous storage devices fromdifferent vendors or from the same vendor.

The network 104 may comprise a local area network (LAN), storage areanetwork (SAN), wide area network (WAN), the Internet, an Intranet, etc.

In certain embodiments, the backup/restore client 114 and thebackup/restore server 118 may operate according to a common Internet ofThings protocol that all appliances and backup servers may utilize toprovide common backup and recovery services. For instance, themanufacturers or distributors of the network attached appliances 100 ₁,100 ₂ . . . 100 _(m) may contract with operators of backup servers 102₁, 102 ₂ . . . 102 _(n) who provide backup/restore services for networkattached appliances 100 ₁, 100 ₂ . . . 100 _(m) of different types fromdifferent vendors so that the backup and restore services may beubiquitous within the Internet of Things. Further, the backup andrestore operations and communications among network attached appliancesand backup servers may be session free, requiring no registration orauthentication.

FIG. 2 illustrates an embodiment of a configuration setting entry 200_(i) in the configuration setting database 200, such as a databaserecord, for each configuration setting 108 communicated by the networkattached appliances 100 ₁, 100 ₂ . . . 100 _(m), and includes a networkattached appliance unique ID 202, which comprises the unique ID 112 ofthe network attached appliance 100 _(i) providing the configurationsetting 200 that is backed up, and a timestamp 206 of the backed-upconfiguration settings 200. The unique ID may comprise a MAC address,Internet Protocol (IP address), universally unique identifier (UUID), adevice type, a serial number, etc. The unique ID may be defined by theuser of the network attached appliance 100 ₁, 100 ₂ . . . 100 _(m).

FIG. 3 illustrates an embodiment of a backup/restore request 300generated by the backup/restore client 114 and communicated to thebackup servers 102 ₁, 102 ₂ . . . 102 _(n), and includes a service classheader 302 identifying a service class that indicates the request ispart of a backup service, and devices, such as the backup servers 102 ₁,102 ₂ . . . 102 _(n) and network attached appliances 100 ₁, 100 ₂ . . .100 _(m), may listen for broadcasts having this service class associatedwith the backup service; a request type 304, such as backup or restore;a unique identifier 306 of the network attached appliance 100 ₁, 100 ₂ .. . 100 _(m) initiating the backup or restore request; configurationsettings 308 at the network attached appliance 100 ₁, 100 ₂ . . . 100_(m) identified by the unique ID 306 if the request type 304 is a backuprequest; and a timestamp 310 of the provided configuration settings 308.For a restore request to restore configuration settings, the requesttype 304 would indicate restore and there would be no configurationsettings 308 nor timestamp 310 included.

With the backup request 300 of FIG. 3, the configuration settings tobackup are tagged with the header and unique ID of the network attachedappliance 100 ₁, 100 ₂ . . . 100 _(m) generating the backup request 300.

FIG. 4 illustrates an embodiment of a restore reply 400 generated by thebackup/restore server 118 in response to a restore request 300 from anetwork attached appliance 100 ₁, 100 ₂ . . . 100 _(m), and includes theservice class header 402 used to identify those devices participating inthe backup/restore services; a restore code 404 identifying the reply400 as having information for a restore; a network attached applianceunique ID 406 of the network attached appliance 100 ₁, 100 ₂ . . . 100_(m) that initiated the restore request; the configuration settings 408to restore at the requesting network attached appliance 100 ₁, 100 ₂ . .. 100 _(m); and a timestamp 410 of the configuration settings 408.

FIG. 5 illustrates an embodiment of operations the backup/restore client114 in the network attached appliances 100 ₁, 100 ₂ . . . 100 _(m)performs to backup configuration settings 108 in the backup servers 102₁, 102 ₂ . . . 102 _(n). The operations of FIG. 5 may be periodicallyinitiated at the network attached appliances 100 ₁, 100 ₂ . . . 100 _(m)to periodically backup the configuration settings 108. Upon initiating(at block 500) a backup of the configuration settings 108, configurationsettings 108 are gathered (at block 502) at the network attachedappliance 100 _(i) and the unique ID 112 is determined (at block 504). Abackup request 300 _(B) is generated (at block 506) including a serviceclass header 302, a backup request type 304, the determined unique ID306, the gathered configuration settings 308, and the timestamp 310. Thegenerated backup request 300 _(B) is broadcasted (at block 508) throughthe network adaptor 116 to the backup servers 102 ₁, 102 ₂ . . . 102_(n) in the network.

In one embodiment, the backup request 300 _(B) may be broadcasted on thenetwork 104 to be received by every device in the network 104. In afurther embodiment, the backup request 300 _(B) may be transmitted usingdifferent transmission protocols, such as a transmission to an addressedbackup server or a multicast, so that devices in the network 104 thatare members of the service class for backup services indicated in theservice class header 302 would receive and process the backup request300. Thus, in described embodiments, those devices, such as networkattached appliances 100 ₁, 100 ₂ . . . 100 _(m) and backup servers 102₁, 102 ₂ . . . 102 _(n), participating in the backup/restore serviceclass would receive and process backup requests 300 _(B).

FIG. 6 illustrates an embodiment of operations the backup/restore client114 in the network attached appliances 100 ₁, 100 ₂ . . . 100 _(m)performs to generate a restore request 300 _(R). The restore request 300_(R) may be initiated by a user wanting to restore the configurationsettings after a failure or upon replacing a network attached appliance100 ₁, 100 ₂ . . . 100 _(m). Upon initiating (at block 600) theoperation to generate a restore request, the backup/restore client 114generates (at block 602) a configuration restore request 300 _(R)including the service class 302, network attached appliance unique ID306 of the network attached appliance 100 _(i) wanting to restore itsconfiguration settings, and a restore request code in the request type304. The generated restore request 300 _(R) is broadcasted (at block604) through the network adaptor 116, which would reach the backupservers 102 ₁, 102 ₂ . . . 102 _(n) in the network 104 listening forsuch request. In this way, multiple of the backup servers 102 ₁, 102 ₂ .. . 102 _(n) may receive the restore request 300 _(R), and thebroadcasting network attached appliance 100 _(i) is not aware of thebackup servers 102 ₁, 102 ₂ . . . 102 _(n) that have received andbacked-up the restore request 300 _(R).

FIG. 7 illustrates an embodiment of operations performed by thebackup/restore server 118 executing in the backup servers 102 ₁, 102 ₂ .. . 102 _(n) to process requests from the network attached appliances100 ₁, 100 ₂ . . . 100 _(m), including a backup request 300 _(B) andrestore request 300 _(R). Multiple of the backup servers 102 ₁, 102 ₂ .. . 102 _(n) may process and perform backup and restore operations forone backup 300 _(B) and restore 300 _(R) request broadcasted from one ofthe network attached appliances 100 ₁, 100 ₂ . . . 100 _(m). Thebackup/restore server 118 may listen for broadcasts of backup andrestore requests 300 from the network attached appliances 100 ₁, 100 ₂ .. . 100 _(m). Upon receiving (at block 700) a communication, if (atblock (702) the communication does not indicate a service class 302associated with backup services, i.e., does not comprise a backup 300_(B) or restore 300 _(R) request, then the communication is discarded(at block 704) and not further processed. If (at block 702) the serviceclass identified in the header 302 is associated with backup services,then the backup/restore server 118 determines (at block 706) whether thebackup services request type 304 is a backup or restore request. If abackup request, then the backup/restore server 118 generates (at block708) a configuration setting entry 200 _(i) in the configuration settingdatabase 200 including the network attached appliance unique ID 306,configuration settings 308, and timestamp 310 in the backup request 300in fields 202, 204, and 206, respectively, to store in the configurationsetting database 200.

If (at block 706), the backup services request is a restore request, asindicated in the request type 304, then the backup/restore server 118determines (at block 710) whether there is a configuration settingsentry 200 _(i) in the database 200 having a unique identifier 202 thatmatches the unique identifier 306 in the restore request 300 _(R). If(at block 710) there is no configuration setting entry 200 _(i) for theunique identifier 306 in the restore request 300 _(R), i.e., for therequesting network attached appliance 100 _(i), then the restore request300 _(R) is discarded (at block 712).

If (at block 710) there is a configuration setting entry 200 _(i) forthe unique identifier 306 in the restore request 300 _(R), then thebackup/restore server 118 generates (at block 714) a restore reply 400including the service class header 402 indicating backup services, therestore code 404; and in fields 406, 408, and 410 the unique networkattached appliance ID 202, 306 in the configuration setting entry 200_(i) and restore request 300 _(R), the configuration settings 204, andthe timestamp 206 in the configuration setting entry 200 _(i) in theconfiguration setting database 200. The generated restore reply 400 isbroadcasted (at block 716) to the devices in the network, including thenetwork attached appliances 100 ₁, 100 ₂ . . . 100 _(m), in the network104. In this way, multiple of the network attached appliances 100 ₁, 100₂ . . . 100 _(m) may receive the restore reply 400, and the broadcastingbackup server 102 _(i) is not aware of the different network attachedappliances 100 ₁, 100 ₂ . . . 100 _(m) that will receive and process therestore reply 400.

With the operations of FIG. 7, each of the backup servers 102 ₁, 102 ₂ .. . 102 _(n) may independently listen for backup 300 _(B) and restore300 _(R) requests and store the configuration settings broadcasted frommultiple of the network attached appliances 100 ₁, 100 ₂ . . . 100 _(m)in backup requests 300 that are broadcasted to all the backup servers102 ₁, 102 ₂ . . . 102 _(n) that are intended to receive the backuprequests 300 _(B), such as in the same service class. In this way, thenetwork attached appliances 100 ₁, 100 ₂ . . . 100 _(m) are not aware ofwhich backup servers 102 ₁, 102 ₂ . . . 102 _(n) in the network 104received and stored the configuration settings 108. Further, whenbroadcasting a restore request 300 _(R), the backup servers 102 ₁, 102 ₂. . . 102 _(n) are not aware of the network attached appliances 100 ₁,100 ₂ . . . 100 _(m) that have received the restore reply 400 andapplied the configuration settings 409.

FIG. 8 illustrates an embodiment of operations performed by thebackup/restore client 114 in the network attached appliances 100 ₁, 100₂ . . . 100 _(m) to process a received restore reply 400 from one of thebackup servers 102 ₁, 102 ₂ . . . 102 _(n). The backup/restore client114 may listen for broadcasts of restore replies 400 from backup serversin the network 104. Since each of the backup servers may independentlyrespond to a restore request 300 _(R), the network attached appliances100 ₁, 100 ₂ . . . 100 _(m) may receive multiple restore replies 400from the backup servers 102 ₁, 102 ₂ . . . 102 _(n) for the same restorerequest 300 _(R). Upon receiving (at block 800) the restore reply 400,if (at block 802) the service class header 402 in the restore reply 400does not indicate the service class associated with the backup services,then the restore reply 400 is discarded (at block 804) and not furtherprocessed. If (at block 802) the service class identified in the header402 is associated with the backup services, then the backup/restoreclient 114 determines (at block 806) whether the unique ID 406 in therestore reply 400 matches the unique ID 112 of the receiving networkattached appliance 100 _(i). If (at block 806) there is not a match,then control proceeds to block 904 to discard the restore reply 400,because it is intended for a different network attached appliance. If(at block 806) there is a match and the restore reply 400 is intendedfor the receiving network attached appliance 100 _(i), then adetermination is made (at block 808) whether the timestamp 410 for theconfiguration settings 408 in the restore reply 400 is greater than thetimestamp of the last applied configuration settings 108 in the networkattached appliance 100 _(i). If (at block 808) the timestamp is notgreater, meaning the current installed configuration settings 108 arecurrent, then control proceeds to block 904 to discard the restore reply400. If (at block 808) the timestamp 410 indicates the configurationsettings 408 are more current than the currently installed configurationsettings 108, then the configuration settings 408 are applied (at block810) to the network attached appliance 100 _(i). If there are noinstalled valid configuration settings 108, such as if the configurationsettings 108 have been corrupted, then the configuration settings 408 inthe restore reply 400 are automatically applied.

The operations to apply the configuration settings 408 at block 808 maybe alternatively performed by applying the configuration settings 408 inthe first received restore reply 400 ₁, and then discarding anysubsequently received restore replies.

With the operations of FIG. 8, the backup/restore client 114 may processrestore replies 400 from multiple backup servers 102 ₁, 102 ₂ . . . 102_(n) responding to the same broadcasted restore request 300 _(R).

Described embodiments provide techniques for an embedded backup/restoresystem in network attached appliances to backup and restoreconfiguration settings to multiple backup servers in the network, suchthat a single backup and restore may be broadcasted to multiple of thebackup servers on the network to independently process. Each of thebackup servers may independently store configuration settings for eachof the network attached appliances to provide redundancy in the storageof the configuration settings. The embedded system of the describedembodiments may thus broadcast backup and restore requests without beingaware which of the one or more backup servers will process, and thus beable to process multiple responses to a single restore request from thedifferent backup servers in the network that may simultaneously receivebackup and restore requests from the network attached appliances. Thebackup and restore operations and communications among network attachedappliances and backup servers may be session free, requiring noregistration or authentication.
